Sink Repair Cost 2026: Kitchen & Bathroom Prices by Problem

A clogged or leaking sink rarely feels urgent until the water starts pooling in the cabinet below. By then, most homeowners want a fast answer on price before they call anyone out. Sink repair covers a wide range of jobs, from a simple clog to a cracked basin that needs full replacement. Kitchen sinks tend to cost more to fix than bathroom sinks, mostly because of garbage disposals and double-basin plumbing.

The gap between a kitchen and a bathroom sink repair surprises a lot of homeowners who assume a sink is a sink. In practice, the plumbing behind a kitchen sink is closer to a small system, with a disposal, a dishwasher line, and sometimes two basins sharing one drain, while a bathroom sink is usually a single basin with one drain and one supply line each for hot and cold.

Quick Answer: Sink repair cost typically runs $125 to $350 for a standard flat-rate job. Simple clogs run closer to $75 to $250, while kitchen sinks with a garbage disposal or double basin often land at the higher end.

Sink Repair Cost by Type

Sink Issue	Typical Cost Range
Simple clog or slow drain	$75 – $250
Leaking drain assembly or P-trap	$125 – $300
Garbage disposal repair (kitchen)	$150 – $400
Cracked or chipped basin	$200 – $450
Faucet repair at sink	$150 – $350
Double-basin plumbing repair	$200 – $450
Pedestal or vessel sink reseal (bathroom)	$150 – $350

Kitchen Sink Repair Cost vs. Bathroom Sink Repair Cost

Factor	Kitchen Sink	Bathroom Sink
Average repair cost	$150 – $400
Common extra component	Garbage disposal, dishwasher line	Pop-up drain stopper
Typical basin count	1 or 2	Usually 1
Most common failure	Clog from grease or food	Clog from hair and soap, or a loose stopper

Kitchen sinks see heavier daily use and handle food waste, grease, and dishwasher runoff, all of which contribute to more frequent clogs and a wider range of possible repair needs. Bathroom sinks fail less often, but when they do, the fix is usually just as fast and often cheaper.

What Affects the Price of a Sink Repair

Kitchen vs. Bathroom Sink

Kitchen sinks usually involve more plumbing: a garbage disposal, a dishwasher drain line, and sometimes a double basin. Bathroom sinks are simpler, which generally keeps their repair costs lower.

Material of the Sink

Stainless steel and porcelain sinks are common and inexpensive to work around. Stone composite or farmhouse sinks can be heavier and harder to access, which can add to labor time.

Cause of the Problem

A simple hair or grease clog clears quickly. A cracked basin, a failed garbage disposal, or corroded pipes under the sink take longer to diagnose and fix, and often cost more.

Age of the Plumbing

Older homes with galvanized or cast iron drain lines under the sink sometimes need extra work just to safely access the clog or leak, which adds to the final bill.

Sink Mounting Style

A drop-in sink is the simplest to work around. Undermount sinks, which attach to the underside of the counter, and pedestal sinks, which hide plumbing inside a column, both take extra time to access during a repair.

Common Sink Problems and Their Fixes

Slow or Clogged Drain

Most kitchen clogs come from grease, food scraps, or soap buildup. A plumber typically snakes the line or uses a hydro jet for a stubborn clog.

Leaking Under the Sink

This usually traces back to a loose P-trap connection, a cracked drain assembly, or a worn supply line. These are common, quick fixes once the source is found.

Garbage Disposal Not Working

Jams, worn blades, or electrical issues are the most common causes. Some disposals can be reset or cleared, while others need a full replacement, which costs more than a simple repair.

Cracked or Chipped Basin

Hairline cracks sometimes allow a sealant repair. Larger cracks or chips usually mean the basin needs to be replaced rather than patched.

Pop-Up Drain Stopper Not Sealing

Common on bathroom sinks, a worn or misaligned stopper lets water drain out even when closed. This is a fast, inexpensive adjustment or part swap in most cases.

Loose or Wobbly Pedestal Sink

Over time, the mounting bolts securing a pedestal sink to the wall can loosen, making the whole fixture feel unstable. A plumber can usually re-secure it without removing the sink entirely.

What a Plumber Checks During a Sink Repair Visit

Whether the clog is isolated to the sink or affects other drains in the home, which can point to a bigger line issue.
The condition of the P-trap and drain assembly for cracks, corrosion, or loose connections.
Supply line and shutoff valve condition, since a failing valve can mimic a sink leak.
For kitchen sinks, the garbage disposal mounting and electrical connection if it is part of the complaint.
The basin itself for hairline cracks that may not be visible until the surface is dry.

Sink Repair vs. Sink Replacement

Repair is almost always the cheaper first step for a working sink with one isolated problem. A full sink replacement, including a new basin and reconnecting plumbing, usually runs $300 to $800 depending on the sink type. Replacement becomes the better option when the basin is cracked beyond repair, when the sink is original to a home more than 20 years old, or when the cost of repeated small repairs starts to add up.

Stainless steel sinks are among the easiest and cheapest to replace if repair no longer makes sense. Stone composite, farmhouse, and vessel sinks cost more to replace, which is one more reason repair is usually worth attempting first on these styles.

How to Prevent Future Sink Clogs

Run hot water for a few seconds after using the kitchen sink to help flush grease through before it cools and sticks to the pipe walls.
Use a drain strainer in both kitchen and bathroom sinks to catch food scraps, hair, and soap residue before they enter the pipe.
Avoid pouring coffee grounds, rice, pasta, or grease down the kitchen drain, even with a garbage disposal running.
Run cold water while operating the garbage disposal, which helps solidify grease so it can be chopped and flushed through rather than coating the blades.

How to Save Money on Sink Repair

Try a plunger or a basic drain snake on a slow drain before calling a plumber for a simple clog.
Avoid pouring grease or coffee grounds down the kitchen sink, since these are the top cause of repeat clogs.
Ask whether a sink repair and a related faucet repair can be done in the same visit to save on a second service call.
Get a flat quote in advance for garbage disposal issues, since diagnosis time can vary a lot by model.

Signs You Need a Professional

Water backs up into a second sink or the bathtub when you run the kitchen sink.
There is a bad smell coming from the drain that cleaning does not fix.
You see standing water in the cabinet below the sink.
A snake or plunger has not cleared the clog after two attempts.
The basin has a crack that lets water seep through to the cabinet below.

Regional Cost Differences for Sink Repair

Region	Typical Sink Repair Cost
Northeast (NY, MA, NJ)	$150 – $400
West Coast (CA, WA, OR)	$150 – $400
Midwest (OH, IL, MI)	$100 – $275
South (TX, FL, GA)	$100 – $300
Mountain West (CO, UT, AZ)	$110 – $300

As with most plumbing work, the difference between regions comes down to labor rates rather than the cost of parts, since a P-trap or garbage disposal costs roughly the same no matter where it is installed.

Garbage Disposal Repair vs. Replacement

A failing garbage disposal is one of the more common reasons homeowners search for sink repair cost, and it is worth treating as its own decision separate from the rest of the sink.

Situation	Recommended Action
Disposal is jammed or tripped	Reset or clear, usually under $150
Disposal is leaking from the base	Repair or replace, $150 – $400
Disposal is more than 10 years old and failing	Replace, $200 – $600 installed
Disposal makes a burning smell or will not reset	Replace immediately, do not continue using it

A disposal that trips its reset button repeatedly, or gives off a burning smell, should be unplugged and replaced rather than repeatedly reset, since this usually signals a failing motor that can become a safety issue.

Frequently Asked Questions

Chemical drain cleaners often only clear part of a clog or move it further down the pipe. A plumber’s snake or hydro jet reaches clogs that store-bought products cannot.

It is usually a simple, inexpensive fix, but left alone it can soak the cabinet floor and lead to mold. It is worth fixing as soon as you notice water pooling.

Small hairline cracks can sometimes be sealed. Cracks that go through the basin or affect the drain opening usually require full replacement.

This is often a dry P-trap, which lets sewer gas rise through the drain. Running water for a minute usually refills the trap and fixes the smell.

Repair typically runs $150 to $400. A full replacement, including the new unit, usually costs $200 to $600 installed, depending on the model.

It depends on the problem. A slow drain is usually safe to use carefully, but a leaking supply line should be shut off at the valve until a plumber arrives.

They have more connection points and often share a single drain line. This means a plumber has more plumbing to inspect and more potential leak points to check.

Stainless steel sinks often last 15 to 30 years. Porcelain and stone composite sinks can last even longer if they are not chipped or cracked.

Rarely. Most clogs clear from the drain opening or by removing the P-trap. This takes a few minutes without removing the sink itself.

Many home warranty plans cover plumbing system failures but exclude clogs caused by misuse, like flushing grease or food waste down the drain.

This usually means the mounting bolts have loosened over time. A plumber can retighten or replace them without needing to remove the entire sink.

Basic drop-in sinks can sometimes be swapped by an experienced DIYer, but undermount and vessel sinks involve sealing and support work best left to a professional.

Hair and soap scum gradually coat the inside of the drain pipe, narrowing the space water flows through until a full clog eventually forms.

Cast iron sinks are durable and often worth repairing, since chips can be touched up and the material itself rarely wears out structurally.

Final Thoughts

Sink repair cost usually falls between $125 and $350, though kitchen sinks with a disposal or double basin can push past that range. Most problems trace back to a clog, a loose connection, or a worn part, all of which are quick fixes for a licensed plumber. Before calling for service, try a plunger on a simple clog and check for loose connections under the sink. If the sink is older or has needed repeated repairs, it may be time to weigh full replacement against another service call.
